GeForce RTX 2080 SUPER vs GeForce RTX 3090 specs and performance
For gaming, the GeForce RTX 3090 graphics card is better than the GeForce RTX 2080 SUPER in our tests.
In our comparison, the GeForce RTX 2080 SUPER has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the GeForce RTX 2080 SUPER also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.
Furthermore, the spec sheet for both these GPUs show that the GeForce RTX 3090 has significantly more memory with 24 GiB of memory compared to 8 GiB. Lots of memory is good when playing at high resolutions or with many monitors.
In addition, the GeForce RTX 2080 SUPER has a slightly lower TDP at 250 W when compared to the GeForce RTX 3090 at 350 W. TDP (Thermal Design Power) measures total heat output from the chip.
In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 3090 over the GeForce RTX 2080 SUPER.
